amd更适合什么内存条(amd平台上什么内存条好)

G41 and mobile platform chipsets of the same era can only accept memory modules with a single memory particle size less than 256M.
Li Ergou next door bought a 4G memory stick with 8 memory chips on the front and back. His old MAC mini couldn’t light up, so he angrily asked the merchant to return it. It was really a problem with the memory stick. What? No, because chipsets starting with 4, such as G41/GM41/P41/PM41/PM45/PM43, can only recognize memory chips below 256M, so the merchant said that he does not take responsibility for this, and you need to pay for the return shipping. In order to avoid this situation, if your computer is the above-mentioned old platform, how do you know whether the memory you are about to buy can be used? It is very simple, just divide the capacity by the number of particles present on it. As long as it is less than 256M, feel free to buy it.
2. For the 3rd generation memory sticks that are the most popular nowadays, pay attention to distinguish between standard voltage and low voltage memory sticks.
After the Haswell platform, many computers only support low-voltage memory sticks (not all). These computers need to purchase DDR3L memory sticks. The working voltage of this kind of memory stick is 1.35V, while the standard The operating voltage of DDR3 is 1.5V. Please pay attention to the difference when purchasing memory modules. (Actually, the chip that determines the working voltage of the memory stick is called SPD. If you know how to flash, you can add another working voltage to your memory stick to make it "fully compatible")
verification memory Must it not be used on ordinary computers?
The answer is not necessarily. If the verification memory in your hand is pure ECC verification memory, then congratulations, this kind of memory module can be directly installed and used as an ordinary memory module. If the verification memory in your hand is ECCreg mode verification memory, then you probably need the support of the server chipset to light it up, such as X58 (the real X58 is not modified with the H55 Southbridge) X79 (the real X79 is not H61B75 magic modification). Let me remind you that many copycat brand X series motherboards are made of ordinary chipsets such as H61, which are made by modifying the CPU base to have 2011 pins. This kind of motherboard is easy to break, and it is also a useful commodity for JS to make money.
4. How to choose memory for AMD platform and APU?
The AMD platform, especially the APU, is very dependent on dual-channel memory. When we purchase this kind of platform, we must choose dual-channel high-frequency memory modules for installation. For example, if you choose the 3rd generation When installing Ryzen 3200G, you must not consider memory modules with a frequency of 2133. At least a memory module with a frequency of 2666 or even higher must be installed. And you must buy dual-channel memory. If you need 16G, buy two 8G ones. So on and so forth.
is AMD special memory module?
AMD special memory modules are generally produced by small factories and are assembled from retired ECCreg 4bit particles. Generally, only the server chipset can recognize 4bit particles, but AMD This technology was decentralized to all its CPUs (AMD’s memory controller is in the CPU, while Intel’s is in the chipset. Seriously, Pentium 3 can use DDR4 memory sticks as long as a master is willing to modify it. , it’s just that you can’t use such a high frequency. I have seen the oldest Pentium 4 motherboards with 423 pins using DDR3 slots, and there are many free fish. If you are curious, you can take a look). Almost all AMD motherboards can use this memory. It is a bonus, you can buy it with confidence, and there are generally no big problems.
Intel has miraculously supported this kind of particles since the 6th generation. For example, if 9100F is paired with the H310DDR3 version, you can use this cheap memory stick to reduce the installation cost, but it has also become a way for JS to make money. means. After all, there is still a price difference in memory.

The particles used in AMD dedicated module are 4bit wide. This kind of memory particles are generally used in server memory modules, but other K8 or K10 The memory controller integrated in the core architecture AMD processor supports 4bit particles.
AMD is a memory module used in servers. In fact, it cannot be said that it is an AMD-specific stick. It is actually a compatibility issue with the memory stick. A certain motherboard chip can be compatible. This kind of memory stick can only be used on most AMD CPUs.
The way to tell whether a memory stick is AMD-specific is as follows: when you buy it, it will be specifically written as AMD-specific. If not, you need to look at the specifications on the flash memory particles of the memory stick. If it is 4bit, it is AMD-specific.
Onda ddr31600 is amd special memory module. According to the relevant information, Onda DDR31600 uses AMD's special DDR3 strip and has 8G of memory, which can store the calculation data of the CPU and exchange data with the hard disk external memory. Onda DDR31600 motherboard provides two AMD memory slots.
The bit width of the AMD special strip is 4bit, and the particles are removed from the server memory. Because Intel's CPUs only allow 8-bit wide memory, but AMD does not require it, a batch of 4-bit server memory modules appeared that Intel could not use but AMD could use.
SK Hynix memory modules are an example: the technical level is different. Ordinary memory generally uses 8-bit particles. The AMD-specific one uses 4bit particles. The scope of application is different. Ordinary memory has a wider application range, while AMD-specific memory is only suitable for use on AMD platforms. Performance is different.

AMD dedicated memory is a type of memory that can only be used on the AMD platform.

The server memory chips used in AMD's dedicated memory are 4-bit standard, and the scope of use of 4-bit standard memory chips defined in international standards is server PCs, and Intel products are Designed in accordance with international standards, Intel's host memory can only recognize 8bit*1bank, 8bit*2bank, and 16bit*1bank; if a memory stick made with 4bit chips is plugged in, it will not be recognized.

AMD has decentralized server technology to the PC, so AMD motherboards accept a wider range of memory, 4bit* (1bank&2bank), 8bit* (1bank&2bank), 16bit* ( 1bank & 2bank) are no problem.

Extended information:

The difference between AMD dedicated memory and ordinary memory:

Technically speaking, ordinary qualified memory uses 8-bit particles, with 8 bits on one side. A particle (chip) with a total of 64 bits is called 1rank; 128 bits on both sides is called 2rank. AMD's special strip uses 4-bit chips, with only 32 bits on one side and 64 bits on both sides, which is half the width of normal memory.

The impact of memory on the performance of the entire machine is still very obvious, and large capacity does significantly improve the player's gaming experience, but for ordinary players, it is still recommended to choose regular memory.

This kind of memory is not recognized in Intel's memory specifications, so it cannot be recognized, or only half of the capacity can be recognized; but after counterfeiters modify it in the memory EP-ROM (equivalent to the motherboard's BIOS) Counterfeiting and counterfeiting can deceive AMD's memory controller. AMD mistakenly thinks it is normal 128-bit memory, can identify the capacity, and seems to work normally. It is easy for memory address overflow to occur, causing a blue screen of crash.

Some AMD special strips are used by small workshops to remove the chips from obsolete server memory and re-solder them to the memory PCB board. Due to the number of memory digits, these memories have 4 banks on one memory. AMD's memory controller is integrated in the CPU and can recognize the 4 banks on the memory, while Intel's motherboard can only recognize each bank. There are 2 banks of memory, so sometimes only half of the capacity is recognized, and sometimes it cannot be started.
